About this course

This course builds trigonometry fluency from fundamentals to confident precalculus-level problem solving. It develops angle measure in degrees and radians (including conversions, arc length, and sector area), right-triangle trigonometry and modeling, and unit-circle definitions with exact special-angle values and sign analysis. It connects trig functions to graphs and transformations (amplitude, period, phase/vertical shifts), introduces inverse trig with domain/range interpretation, and practices core identities for simplification and verification. It also covers solving common trig equations, Law of Sines/Cosines for non-right triangles, and applications such as heights/distances, bearings, vectors, and periodic phenomena.
